The Draugen FSL system comprises seabed bases for flowlines from the main platform, vertical risers kept buoyant by subsurface buoys, swivel arrangements allowing tankers to weathervane, and flexible hoses for crude transfer. Installed subsea, FSL supports continuous export of oil without a dedicated surface buoy or secondary platform; navigation and positioning systems ensure safe tanker rendezvous. The infrastructure integrates with the Draugen platform's export flowlines, control systems for load monitoring, emergency shutdowns, and subsea metering equipment. Utility systems are minimal compared with a platform but include subsea communications, valve control umbilicals, and riser support structures designed for North Sea conditions. The FSL is engineered for reliability and pigging capability of export lines.
